To all/"whom it may concern:

Be'it known that we, Rnnon W. Pnnss and Ci-IARLns VVILLY SGHWENZFEIER,citizens of the United States, residing at Glassboro, in the county ofGloucester and State of New Jersey, have invented new and usefulImprovements in Electrical Recording rip paratus, of which the followingis a spec1lication. 7

Our invention relates to electrically operated indicating and rec rdingapparatus adapted to indicate and record the speed, output, orperformance at all times of a machine or apparatus which is doing work.

A. feature oi the invention consists in providing, in combination with arecording instrument, a suitable electric generator having its fieldwindings connected with a con-' stant potential circuit, so that anoperating current will be supplied to said instrument substantiallyproportional to the speed of the machine or apparatus whose performanceis to be recorded, the generator being connected to be driven at a speedproportional to said machine or apparatus. The invention is herein shownin I with an automatic bottle making machine. to record the speed,output and stoppages oi the machine.

In the accompanying drawings:

Figure l is as View of an indicator card on which may be recorded theperformance of a bottle machine.

Figure 2 is a fragmentary view of a bottle machine, its motor, and agenerator supplying current to the indicating and recording instruments.

Figure 3 is an elevation of the motor and generator.

Figure 4 is an end view of the same, the generator being shown insection, the in cheating and recording instruments also being shown.

An automatic glass blowing machine A comprises a mold carriage 8 whichrotates -ontinuously about a vertical axis, being driven by a motor Mthrough a suitable train of gearing. Mounted on the mold carriage is aset of molds in which the bottles 9 are blown and from which they aredischarged seriatim; Reference may be had to patent to La France,#1,185,687, for a detailed disclosure of such a machine.

In order to indicate and record the perconnection :tormance of themachine, a recording indicator R is provided which is excited by anelectric current {from a generator G which is connected to run insynchronism with and a speed proportional to that of the chine A.As'herein shown, the generator is directly connected through a flexiblecoupling 10 to the motor shaft. The motor M is supplied with currentfrom any suitable source and as here shown is connected to the directcurrent constant potential mains 1'1, and. 12. The generator G is adirect (llli'ellt generator and has its field windings connected to anysuitaliile sour a, constant potential, and as herein shown is connectedthrough conductors l3 and i l to themains 11 and 12. The strength of thegenerator field is, therefore, substantially constant for all speeds oithe generator and,

the potential of the generator brushes substantially pro'portirmal tothe speed of the generator.

Conductors i5 and 16 lo d from the generator brushes to the recordingmeter it which may be of standard construction and which comprises anarm 17 arranged. to swing radially across'the face of an in dicator card18 on the recording instru ment. The indicator card is provided withappropriate markings for indicating and recording the performance of aparticular type or character of machine with which the instrument may beused. As herein shown, this card is designed to indicate in bottles perminute, the output of the glass blowing machine with which it isconnected. For this purpose the card comprises radially disposed lines19 indicating hours and onequarter hours. Concentric circles 20 aredesignated by Figures 21 which represent the output of the machine inbottles per minute. The arm 17 is provided, as is usual in instrumentsof this character, with a recording stylus which swings radially acrossthe face of the card, the position of the stylus being all timesdetermined by the speed of the generator. The indicator R comprises theusual clockwork for rotating the disk. The stylus will, therefore,

record on the disk a line or marking (which may, for example, be in redink) which indicates the operation of the machine. The card, as shown,is adapted for a twentyfour hour record and records the speed of .iuenachine J. .4- anc lei shat ilulicate achiue, the k aduated to1-.olutions per ininuc ot the bottle, or the nni'uber Q1 bottles per be:(Hlllitt ed to the to at any time the s dial ot the indicator being;indie may he irei'l. The indic ors I nl at any conimiient he machineoorl ti -t although the adapted to in l "i a glass Jl()\Vl machine, itis not limi"iu to such use. as is it be adapted to indicate the sped,perianie or output oi a 9 at variety of machines or niecluinisins.

Modifications of the construction of the apparatus andv arrancements oi.parts may be made without departing from the spirit and scope of ourinvention.

What we claim is:

l. The combination with a machine and driving means therefor, of anelectric generator connected, to be driven at a speed proportional tothat of the machine, means for exciting the generator held from aconstant potential source independent oi. the speed of said machine, andarecoi'diugg iiulicator actie ated by current su tiplied from thegeneratorand operative to produce a continuoiiis record indicating thespeed ot the machine "for all periods of its operation.

2. The (combination with a machine and driving means therefor, oi anelectric generator connected to be driven at a speed proportional tothat of the machine, means for i 1 nt of the speed oi. machine, arecordi indicator actuated cu rrent supplied from the generator andoperative to produce ontinuous record indicating; the speed of themachine for all periods oi? its operation, said indicator commissing arecordil'm; stylus, and an indicator card having graduated markingsthereon designating the performance of the machine.

3. The combination oif-a machine, means to drive it, a direct currentgenerator, driving connections by which the generator is driven at aspeed proportional to that oi? the machine, constant potential mainsconnected to the generator field windings, and an indicator electricallyconnected to the brushes of the generator and operative to produce acontinuous record indicating the speed oi the machine for all periods ofits o per ation.

in The combination with a continuously rotating gl ss forming nnichinefrom which glass articles termed thereon are periodically dis-icharged,of a direct current generator connected therewith to be driven at aspeed proportional to that ol the machine, a source of constantpotential current from which current is supplied to the iield windingsoi the generator, and a recording indicator electrically onnected to thegenerator to be actuated thereby and comprising a card and an indicatorhaving graduated nnu'kings and designating characters indicating therate at which the articles are delivered by said machine.
